Why are there so few magnetic ferroelectrics?
NA Hill - The journal of physical chemistry B, 2000 - ACS Publications
Multiferroic magnetoelectrics are materials that are both ferromagnetic and ferroelectric in
the same phase. As a result, they have a spontaneous magnetization that can be switched …
